Character of the water
Ösjön lies in central Sweden — a clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
Moderately deep (18 m) — shallow bays, the odd reef and a deeper channel through the middle.
Permits & rules
Fishing permit required — Ösjön FVOF. Day permit ~60 kr · annual permit ~300 kr.
- Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.
- Handheld tackle only. Respect the protected zones at the inlets and outlets.
Species in Ösjön
perch predatory fish
typically ~22 cm · can reach 45 cm
Perch moves carefully in the clear water — small mouthfuls, many of them.
ål fish
typically ~55 cm · can reach 110 cm
Ål holds the bottom even in clear water — shade and depth are its cover.
elritsa fish
typically ~7 cm · can reach 12 cm
Here elritsa lives on the small stuff — and rewards those who fish small and fine.
trout salmonids
typically ~35 cm · can reach 70 cm
In the clear water trout picks its moments — wary, but relentless once committed.
Fishing Ösjön
perch and trout sit at the top of the food chain in Ösjön, carried by ål and elritsa. The clearer water makes the fish wary — and rewards a careful presentation.
The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Ösjön are alike.
General rules of thumb for this kind of water
- Clear water makes fish light-shy — dawn, dusk and night are usually best.
- In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
